The propeller is intended for a new drainage pump at Kolindsund.

2000 liters per second. 850 mm in diameter. Approximately 70 kg.
These are some of the specifications of the propeller that has just been completed at our five-axis machining center.
It will be used in one of the pumps we are building for Kolindsund in Djursland.

The propeller will help pump water away from the fields in the area, which would be Denmark's largest lake if it were not drained.
Since the area lies below sea level, water must always be pumped away—but during periods of heavy rainfall, the pressure on the pumps is intense. This is also why we are dealing with a size where a single pump will move over 2000 liters per second.

The propeller is approximately 850 mm in diameter and has been milled in five pieces. The four propeller blades were milled separately, as was the hub. They were then assembled into a single propeller. Milling the propeller in multiple pieces optimizes both handling and material usage.

The propeller is made of aluminum and still weighs around 70 kilograms when fully assembled. So, it's not something you can just lift with your bare hands.

The pump will be installed in Kolindsund, where in recent years, there have been increasing challenges in pumping away large volumes of water. Especially in the autumn and winter months of last year, large parts of the fields in the area were flooded.
